4.3.1. DC Voltage measurement
CAUTION
Maximum input for DC voltage is 1000V. Do not attempt to take any voltage
measurement that exceeds the limits. Exceeding the limits could cause
electrical shock and damage the multimeter.
Fig. 2: DC Voltage measurement
1. Turn the selector on
V
.
2. Insert the test leads into the jacks, the red plug into
HzV
A
jack and the black
plug into
COM
jack (Fig. 2).
3. Connect the red and black test leads to the positive and negative poles of the circuit
under test respectively. The voltage value will be displayed with automatic detection of
the range.
4. Press
RANGE
key to activate the manual mode; the “AUTO” symbol disappears from
display. Press cyclically
RANGE
to change the position of the decimal point on the
display. To activate the Autorange function keep pressed
RANGE
for at least 1 second.
5. The message "
OL
" means that the voltage exceeds the measuring limits. In this case
disconnect the test leads from the circuit under test to avoid damaging the instrument
or endanger your own safety.
6. The symbol "
-
" on the display means that voltage has opposite direction than shown in
Fig. 2.
7. For minimum and maximum value measurement and HOLD function please refer to
paragraph 4.2.
